Definitions

  • the invention relates to a radiant heating unit for cookers or the like.
  • An object of the present invention is to provide a radiant heating unit of the aforementioned type, which in simple manner can be very accurately secured and aligned with respect to the hotplate.
  • the support tray can be laterally centred with the guide and can also be arranged or mounted in a permanently resiliently adjustable or displaceable manner roughly at right angles to the hotplate, so that a constantly effective sliding guide is formed.
  • a guide with respect to a base i.e. the support tray or several juxtaposed support trays can be arranged in completely freely suspended manner on the bottom of a hob or freewardly outwardly projecting on the outside of a baking oven muffle wall and still permit adjustability of the support tray with respect to the associated hotplate.
  • a considerable reduction in the overall constructional height of the apparatus unit comprising the radiant heater or heaters is obtained and there is no need for a base.
  • the hotplate is generally located in a frame of the associated apparatus unit which surrounds it, said frame being formed by the hob in the case of a cooker and by the muffle wall in the case of a baking oven muffle.
  • the sliding guide can be on the one hand provided between the hotplate and said frame by adjustable mounting of the hotplate with respect to the frame and on the other hand instead of this or in addition thereto between the support tray and the frame, as well as displaceably directly between the hotplate and the support tray, so that through a random combination of these three possibilities and using the same tension springs, numerous adaptations to different requirements can be obtained.
  • the heating resistors can be formed by encapsulated high temperature emitters, namely light bulbs or preferably bare, exposed heater coils or the like.
  • the inventive radiant heating unit is also suitable for heating a baking oven muffle and for similar purposes and in this case the hotplate at least partly forms one wall of the baking oven muffle.
  • the hotplate For connection to the associated apparatus unit, the hotplate need not be directly rigidly fixed and can instead be secured in removable manner with respect to the apparatus unit, e.g. can be tensioned against the sealing profile or merely placed on the frame.
  • the sliding guide can be inwardly displaced with respect to the edge surface of the hotplate and/or with respect to the outside of the support tray formed by the circumference, so that it is completely located within the plan view of the hotplate, e.g. on the inside thereof.
  • the associated end of the sliding guide is then appropriately directly or indirectly fixed with respect to the inside of the hotplate or the support by welding, bonding or the like.
  • Adjacent radiant heaters can be very closely juxtaposed, if the web-like sliding guide engages on the inside of the outer tray, so that there is no need for freely downwardly projecting sliding guide parts engaging over the outside of the support tray.
  • the sliding guide can also engage angularly round the associated edge of the hotplate and adjacent sliding guides of adjacent radiant heaters can be formed in simple manner by a common frame profile, which e.g. simultaneously carries the two adjacent hotplates.
  • the support tray can form a preassembled, integrated component with the hotplate or with the frame carrying the hotplate or hotplates and which as a unit can be adjusted at right angles to its plane, i.e. in the insertion direction of the guides, e.g. for setting purposes, without the tension of the tension springs being influenced.
  • At least one tension spring which is supported with respect to the base, to be preferably arranged in the form of a compression spring between the bottom of the outer tray and a base plate arranged on the associated side of the inner tray.
  • the support tray e.g. the inner tray and outer tray are displaceably guided with respect to one another in the guide displacement direction, as well as spring-loaded.
  • the outer tray can be displaceably mounted in the guide located at the hotplate with respect thereto.
  • FIG. 1 A side view of a hotplate unit provided with radiant heaters according to the invention.
  • FIG. 2 The unit according to FIG. 1 in plan view.
  • FIGS. 3 to 7 Several embodiments for subdivisions of a hob into individual cooking points in a reduced-scale plan view.
  • FIG. 8 A detail of FIG. 1 on a much larger scale and in a sectional representation at right angles to the hotplate.
  • FIG. 9 Another embodiment in a representation corresponding to FIG. 8.
  • FIG. 10 A detail of another embodiment on a larger scale.
  • FIGS. 11 to 13 Three further embodiments in representations corresponding to FIG. 10.
  • FIG. 14 Another embodiment in section.
  • FIGS. 1 and 2 generally several inventive radiant heaters 1 are combined into a heating or cooking point unit, which e.g. forms the upper part of a not shown cooker.
  • Each radiant heater 1 has a support tray 3 located on the underside of a glass ceramic or similar hotplate 4 whose size corresponds thereto.
  • Hotplates 4, in the form of individual plates are located in a frame 5, whose top surface is in the plane of the top of the hotplates 4.
  • Radiant heaters 1, including frame 5 are supported on a flat base 6 formed from crossmembers or the like located beneath the same and which is in turn used for installing the cooking point unit in a cooker, a working plate or the like. As shown in FIG.
  • each support tray 3 has a relatively thick-walled inner tray 7 made from insulating material, e.g. moulded mineral fibres, vermiculite or the like, as well as a sheet metal outer tray surrounding the outer circumference and the underside of the bottom thereof and in which the inner tray 7 is arranged in substantially clearance-free manner in the lateral direction.
  • the rim 9 of inner tray 7 which is set back with respect to the circumferential rim of outer tray 8 engages with pretension on the underside of the associated hotplate 4 around its whole area, along the end face of rim 9 in such a way that it only spacedly contacts hotplate 4 within the outer edge thereof, but adjacent thereto projects slightly outwards over said outer edge.
  • heating resistors 10, 11 in the form of bare, exposed heater coils laid spirally in interengaging spirals are provided on the bottom of the support tray 3 or inner tray 7.
  • hotplates 4 are square, have the same size and are located with a relatively small intermediate gap adjacent to one another, so that four cooking points are formed. However, at least one hotplate, as well as the associated, remaining radiant heater could be circular, oval or the like.
  • An all-round spillage or collecting channel 12 is provided around the field taken up by the cooking points or hotplates 4 and a drain 13 leads away from one side thereof.
  • the spillage channel 12 is formed from frame parts separate from frame 5 and which in the height direction engage in position-variable manner in frame 5, but can be so covered by the latter that in any position any liquid flowing outwards over frame 5 can only pass into channel 12.
  • the frame parts having the spillage channel 12 also form the upright outer shields of the cooking point unit.
  • the substantially rectangular frame having a central cross connection has different profiles on the frame webs 15, located on the outer rectangular sides, than on the inner frame webs 14, forming the cross connection.
  • both outer frame webs 15 and frame webs 14 have in each case a profile web 17 parallel to the immediately adjacent edge surface 16 of particular hotplate 4 and in particular at right angles to the plane of hotplate 4 and a web leg 18 bent from the same and engaging behind the underside of the associated hotplate 4, so that the latter is circumferentially surrounded by angle profiles or sections of the frame webs 14, 15, relative to which the hotplate 4 can be secured in flush manner by bonding.
  • each profile web 17 passes into a cover web 19 or 20 bent therefrom and whose planar top surface is roughly in the plane of the top of the hotplates.
  • the sheet metal outer tray 8 of each radiant heater 1 has a substantially planar bottom 24 engaging in whole-surface manner on the associated side of the inner tray 7 and which passes into an outer jacket 22 roughly at right angles thereto, whose end portion remote from bottom 24 forms an outer rim 23, which is at right angles to the hotplates 4 in the continuous extension of the remaining outer jacket 22.
  • the outer rim 23 of outer jacket 22 engaging in substantially whole-surface manner on the outer circumference of inner tray 7 projects slightly further upwards than end face 25 of bearing rim 9 of inner tray 7.
  • All the outer rims 23 extend with a limited bearing clearance up to the sides of the associated profile webs 17 remote from the particular hotplate 7, but have a relatively large distance between their end edges and the inside of the connecting cover web 19 or 20 and this can be roughly half the height of profile web 17.
  • the width of recess 26 is adapted to the width of web leg 18, whilst its height is at least as great as the spacing of outer rims 23 from cover webs 20, 21.
  • Support tray 3 is pretensioned against hotplate 4 with tension springs 28 uniformly distributed over its circumference and e.g. four such springs located in the vicinity of the corners thereof, whereof only one is shown in FIG. 8.
  • the tension springs 28 in the form of spiral tension springs are located on the insides of cover webs 19, 20 with an alignment at right angles to hotplates 4 and are in each case hung in an angular holder 29 fixed to said inside on the one hand and in an angular holder 30 on the other, which is fixed to the underside of bottom 24 and projects over the outside of outer jacket 22.
  • each tension spring 24 is immediately adjacent to the outside of outer jacket 22 and parallel thereto, the angle legs of holders 29, 30, in which the tension springs 28 are hung are directed against one another.
  • Inner tray 7 can be constructed in one-part or multipart manner and in the latter case has at least one or two bottom layers and also the bearing rim 9 can be formed by a separate ring engaging on the associated bottom layer.
  • the bearing rim 9 can be made from a different insulating material, such as vermiculite particularly suitable for engaging on hotplate 4, whilst the base plate can be made from an insulating material, such as a mineral fibre material suitable for mounting the heating resistors 10, 11 by embedding, as well as for high thermal stresses.
  • Threaded actuating spindles 31 are guided at right angles to hotplates 4 on base 6 and the free ends thereof are supported adjacent to or between tension springs 28 on the insides of cover webs 19, 20.
  • actuating spindles 31 it is possible to adjust the level of the unit comprising hotplates 4, frame 5 and support trays 3 and said spindles 31 can also absorb high weight forces, which can be transferred to base 6, so that frame 5 does not have to have particularly thick cross-sections.
  • FIG. 3 shows an arrangement according to FIG. 2 with four equally large, square and directly adjacent cooking points.
  • FIG. 4 shows two elongated, rectangular, directly juxtaposed cooking points, whose longer extension is directed in the depth direction of the cooker, the length of the cooking points being roughly twice as large as their width.
  • FIG. 5 shows a cooker, in which a single cooking point takes up the entire cooking field, said cooking point being substantially square.
  • FIG. 6 there can be more than two juxtaposed, namely e.g. three juxtaposed cooking points in at least two rows, so that there are in all at least six directly adjacent square or similar cooking points.
  • FIG. 7 there are three parallel, directly adjacent, elongated, rectangular cooking points for forming the cooking field.
  • the particular web leg 18a can pass on its inner edge into a leg web 32 bent away from hotplate 4a which engages in a corresponding groove in or adjacent to the end face 25a of bearing rim 9a and contributes to a further stiffening of the profile or section carrying hotplate 4a.
  • support tray 3a essentially differs from that according to FIG. 8, because the inner tray 7a and the outer tray 8a are mutually displaceably guided at right angles to hotplate 4a, whilst in turn the outer tray 8a is displaceably guided on frame 5a via sliding guides 27a.
  • inner tray 7a On its underside, inner tray 7a has a bottom plate 33, which in the edge region is in the form of shoulder webs 30a for forming reception areas for tension springs 28a between bottom 24a and inner tray 7a.
  • Tension springs 28a arranged between shoulder webs 30a and bottom 24a are constructed as compression springs, e.g. helical compression springs, but can also be leaf springs or the like.
  • actuating spindles 31a Apart from the actuating spindles 31a, there are threaded actuating spindles 35 parallel thereto and guided on base 6a, whose ends are roughly supported in the region on the outside of bottom 24a, in which there is in each case a tension spring 28 a and in each case one spindle 35 and one spring 28a can be equiaxially arranged to one another.
  • actuating spindles 35 are supported on bottom 24a, whilst interposing U-shaped intermediate profiles 34. In each case two adjacent actuating spindles 35 can engage on a common intermediate profile 34.
  • a spindle 31a is positioned between two spindles 35, whilst in the vicinity of frame webs 15a only a single actuating spindle 35 is positioned adjacent to each actuating spindle 31a. If the actuating spindles 31a are adjusted, there is no need to adjust actuating spindles 35, because the frame 5a can be displaced with respect to outer tray 8a by means of sliding guides 27a and consequently there is also movement of the inner tray with frame 5a or hotplate 4a because inner tray 7a is displaceably mounted on outer tray 8a by means of a corresponding sliding guide and is prestressed by tension springs 28a in the adjustment direction.
  • holder 29b is substantially U-shaped and fixed with the outside of a leg directed against profile web 17b to the inside of cover web 20b of frame 5b, e.g. by spot welding.
  • Holder 29b is elastic in such a way that the tension leg 40 can perform articulated movements about a joint axis located in the vicinity of its transition into the U-cross web located parallel to hotplate 4b or to its edge face 16b.
  • the other end of tension spring 28b is hung in a holder 30b bent in one piece out of the bottom 24b of outer tray 8b.
  • Support tray 3b rests with the end face of outer edge 23b of outer tray 8b remote from bottom 24b on the inside of web leg 18b under the tension of tension spring 28b, so that the position of support tray 3b or outer tray 8b is fixed with respect to frame 5b, but at all times it is possible to raise tray 8b from frame 5b either against the tension of tension spring 28b or after removing said tension spring 28b.
  • tension leg 40 Under the tension of tension spring 28b via spring bearing 37, tension leg 40 simultaneously draws support 36 and therefore hotplate 4b against sealing profile 39 in frame 5b, so that if the end face 25b of bearing edge 9b subsides, there is a corresponding adjustment of hotplate 4b with respect to frame 5b, accompanied by the compression of the sealing profile 39.
  • spring bearing 37 If spring bearing 37 is close enough to the inside of outer tray 8b, it can also form a centring for said outer tray aligning the support tray 3b, said centring acting at right angles to that which is formed by the engagement of tension leg 40 in outer tray 8b.
  • Guide rod 41 connected to web leg 18c is at a limited distance from outer jacket 22c of outer tray 8c and traverses a guide channel adapted closely thereto with the necessary movement clearance of the inner tray 7c, as well as the bottom 24c of outer tray 8c, so that immediately below bottom 24c it forms a spring bearing for a tension spring (not shown) supported on the underside of bottom 24c, such as e.g. a leaf spring. If only support tray 3c is adjustably mounted, then the end of guide rod 41 located at hotplate 4c is fixed in stable manner in both directions of its longitudinal extension with respect to frame 5c or hotplate 4c. Said end of guide rod 41 can e.g.
  • guide rod 41d according to FIG. 12 has a solid construction and is e.g. constituted by a threaded spindle, said solid rod being fixed by its end face 42d located at hotplate 4d to the inner leg of support 36d by welding, bonding, rivet joint, threaded engagement or the like.
  • the outer edge 23d of outer tray 3d is once again supported on web leg 18d, so that under the tension of tension springs 28d, hotplate 4d is drawn into frame 5d or against sealing profile 39d.
  • tension spring 28d is a helical compression spring surrounding guide rod 41d, which is on the one hand supported on the bottom 24d of outer tray 8d and on the other hand on a counterholder 29d provided on guide rod 41d and which for forming a control member is constituted by a nut making it possible to adjust the pretension of tension spring 28d.
  • support 36e has no shield web, because it merely has an outer leg running roughly parallel to the edge face 16e of hotplate 4e and terminating between the outside and inside of hotplate 4e.
  • the gap between the edge face 16e and the profile web 17e of frame 5e is closed with a cover seal 43 of silicone or the like, which is connected to edge face 16e and completely covers the associated leg end of support 36e.
  • the tension springs 28b according to FIG. 10 slope outwards, so that with the facing inclined tension springs they secure support tray 3b against lateral movements, i.e. also serve as a guide.
  • outer edge 23 can be provided with an e.g. U-shaped, slipped-on, at least partly elastic profile, e.g. a sealing profile, butt protection profile or the like.
  • This profile e.g. forms a sliding seal with respect to profile web 17 and/or a butt protection with respect to cover web 19, so that the sliding guide is sealed and even if hotplate 4 breaks no liquid can penetrate through the sliding guide into the cooker, whilst a tolerance compensation is also provided.
  • Rim 9 can also be formed by a component made from a better quality or stronger material and which is separate from the remaining inner tray 7.
  • the inventive construction is particularly suitable for providing as the hotplate 4f a non-translucent plate made from a metallic material, such as a cast material and especially cast steel.
  • a metallic material such as a cast material and especially cast steel.
  • Such plates have a much greater breaking strength than glass ceramic plates, so that they are especially suitable for rough use in industrial or commercial kitchens.
  • This plate can also be grounded in a simple manner and also permits a power increase or a rise in the maximum operating temperature.
  • the radiant heating resistors 10f, 11f can be located much closer to hotplate 4f than with a glass ceramic plate, so that an extremely shallow construction is obtained, because the outer rim of support tray 3f can also be made lower.
  • FIG. 14 Such a construction is shown in FIG. 14, in which the same reference numerals as in the remaining drawings are used for corresponding parts, but are followed by the letter "f".
  • the profiling for the engagement of the outer shield provided on the rim of hotplate 4f can also be in one piece with the latter in the represented embodiment and for this purpose it is provided on the inside with corresponding longitudinal grooves 20f adjacent to the edge faces 16f thereof.
  • a corresponding, e.g. rib-like shoulder could be provided on the inside of hotplate 4f, which approximately engages in said inside up to the bend of the leg.
  • the frame 5f directly engaging in hotplate 4f can be constructed in one piece with the outer shield or the collecting channel 12f, so that no separate frame parts are required of this.
  • hotplate 4f As a result of the ribs or profiles 17f, which pass into one another in gap-free manner and at an angle at the intersection points and therefore in each case define an e.g. rectangular or square reception field for the associated radiant heater 1f, it is also possible to achieve an advantageous stiffening of hotplate 4f , so that it can be made relatively thin, have a low weight and also a low heat capacity or absorption.
  • the outermost profile of hotplate 4f adjacent to the particular edge face 16f can either be rib-like, as shown to the left in FIG. 4, or as shown to the right in FIG. 4 can be wider with respect to its height so that it extends approximately up to the reception profiling for frame 5f.
  • the radiant heating elements 10f, 11f are appropriately arranged in such a way that there is a central field no occupied by heating resistors and whose width is greater than the ring width of the heated field surrounding same in circular manner.
  • a thermostat e.g. a thermal cutout, such as an expansion rod regulator, in such a way that the rod-like thermostat is very close to the inside of hotplate 4f and the regulator casing carrying the thermostat is arranged in the central field.
  • the central field can be shielded with a web made from insulating material or the like with respect to the heated field, said web appropriately extending from the inner tray 7f to the inside of hotplate 4 and can be circular, so that a completely closed chamber for receiving the thermal cutout is formed.
  • the web can also serve as the spacer for supporting the central region of the support tray 3f with respect to hotplate 4f.
